Hey Y'all.
My trusty kona hei hei lives on covered porch hooked to a trainer. Is crusted with salt but doing fine.
The middle ring along with big rings are toast again and rather than buy more rings with unusual bcd I'd like to swap the crank. Hopefully someone has experience with this exact frame and can tell me what works.
The bike is still sporting a forged Sugino Impel triple crank with compact gearing (22/34/42). The middle ring is toast, big ring has got some bent teeth. Rather than find another ring I've got some other non-compact cranks with different bcd and good rings that I'd like to swap on.
I tried putting an old road crank but it seemed to sit too close and the 53 ring wouldn't clear the chainstay.
I've got a nice shimano mtb triple crank 26/36/46 to try next, is listed as needing 107-113mm bb for correct chainline. Is that going to fit?
From how tight the current compact gearing fits I'm wondering if this frame perhaps requires a compact crank?
There's a retrobike kona catalog from 1994 shows the bike with a slightly different sugino crank:
But then the usa catalog from 1994 (the one I read before buying the frame) shows the bike with an m900 xtr.That xtr is 107-113mm bb spindle too, so I should be good? Then I look at the parts list at the back of the usa 1994 catalog it shows all xtr except for a kss chromoly bb (same as the hot.)
There's no spindle lengths in the catalog. Perhaps I can deduce what works.
A) kula: un71 + deore xt
B) hot:kss chromoly + deore xt
C) hei hei kss chromoly, xtr
D) A - B -> un71 ~= kss chromoly
E) C - B -> deore xt ~= xtr
D & E -> un71 works with xtr?
So I went and tried the mtn triple with current bb and the rings hit the chainstay. Could be my current bb spindle is too short, but seems like I'm going to need to push those rings out to fit and that will hose chainline?
Anyone rocking a hei hei with non-compact crank? What bb spindle length is working for you? Thanks!
